Aperiodic Monotiles
2023 saw the discovery of an aperiodic monotile: a shape (dubbed 'The Hat') that can tile a plane perfectly, but only without periodicity. To celebrate this inspirational result we organised Hatfest at Oxford University's Mathematical Institute.
I have subsequently worked to understand how physics behaves in these fascinating settings. Some of this work, published in Physical Review Letters, received a write-up here:
Magnetic Monopoles in Spin Ice
Published in Nature.
My experimental collaborators detected signatures of magnetic monopoles in the spin ice material dysprosium titanate, based on our earlier theoretical predictions. You can read some popular summaries here:
